Definitions
- the invention relates to an odor trap for a water outlet and provided with an odor trap drainage.
- a float is arranged up and down over a arranged in a multi-part housing pipe stub, wherein accumulated between the housing and the pipe socket water represents a water barrier for sewer gases, creating a water Odor trap is formed.
- the float dives into the accumulated water. If the accumulated water dries out in the odor trap, the float sinks to the extent of the decreasing level of the water until, in a lowered state, it shuts off the overflow opening formed by the pipe socket, so that gases leaving the channel escape from the drain are prevented by the inlet opening. Only when in turn water flows through the inlet opening into the drain, the float rises. By lifting the float, the overflow is released, and water can flow unhindered through the overflow to the drain opening and through this into the channel.
- a first disadvantage is their large height, which requires a high floor structure of the building. Such a high floor structure is often not feasible eg during renovations. There are also many countries in which a correspondingly high floor construction is not standard or not practical.
- odor traps are also offered on the market with reduced sealing height compared to the standard requirements.
- these miniaturized odor traps have a low drainage performance.
- the problem of non-installability of odor traps due to excessive height occurs especially in barrier-free showers.
- Another disadvantage of the known water odor traps with reduced sealing water level is that they pass through the duct gases when there is an overpressure in the duct system. The reasons for this are on the one hand the drying of the odor trap during prolonged non-use and on the other hand, the low sealing water level in shallow odor closures, so that the sealing water opposes a gas pressure in the channel too little static pressure and therefore can not prevent the passage of channel gases.
- the object of the present invention is to overcome or at least alleviate the said disadvantages of the known water odor traps.
- the height should be reduced compared to the known odor trap while maintaining a sufficient drainage capacity.
- channel gases are to be prevented from passing through the odor trap even with a certain overpressure in the channel system.
- the suction of the sealing water at reduced pressure in the duct system should be reduced.
- the odor trap according to the invention has an odor trap body defining a chamber for sealing water, wherein the chamber has at least one inlet opening and at least one outlet opening, wherein the odor trap has a membrane element movable between a closed position and an open position, which is arranged in the odor trap such that it in the closed position closes the at least one outlet opening of the chamber and in the open position releases the at least one outlet opening of the chamber.
- the odor seal body defines an open drain space that communicates with the at least one outlet opening of the chamber when the membrane element is in the open position.
- the drainage chamber at least partially surrounds the at least one outlet opening of the chamber.
- the at least one inlet opening forms an inlet channel which, viewed in the installation position, has an upper end open to the environment and extends downwards into a lower region of the chamber, the inlet channel at least partially surrounding the discharge chamber.
- This trap has the great advantage that in case of overpressure in the channel, which manifests itself in the drainage chamber of the odor trap, the membrane element is pressed against the outlet opening of the odor trap body and therefore closes the outlet even more firmly.
- Another advantage of the trap is its low height by the provision and positioning of the inlet channels laterally from the drainage chamber.
- the open drainage space also allows mounting positions of the odor trap in each direction of rotation about its vertical axis, i. the installation can be done in 360 ° rotation, if the odor trap has a cylindrical shape.
- a compact construction of the odor trap can be achieved when the at least one outlet opening of the chamber is formed in an inner chamber peripheral wall of the odor trap body, wherein the outer side of the inner chamber peripheral wall defines a part of the drain space.
- the outlet opening is formed by an upper, open end of the inner chamber peripheral wall.
- the outside of a wall portion of the at least one inlet channel defines a part of the drainage space.
- inlet channels are provided, which are arranged spaced apart from one another and surround the outlet opening.
- This embodiment offers the advantage of a large drainage capacity while further reduced height. If two inlet channels are provided, these are preferably offset by 180 ° from one another, ie arranged opposite one another with respect to the outlet space and the outlet opening of the odor trap body, and preferably surround the at least one outlet in sections.
- At least two outlet openings are provided, which are arranged circumferentially spaced apart from each other the inlet channel.
- the odor trap has a lid which is removably disposed on the odor trap body, the lid defines a - in installation position of the odor trap - upper portion of the drain space and seals this upper portion in cooperation with the odor trap body upwards from the environment ,
- the lid may have a transparent window for inspection purposes or be made of a transparent material. Since the lid is removable, the membrane element is easily accessible for maintenance and replacement. The possibility of inspection with the provision of a transparent lid allows a rapid control of the functionality and any contamination of the odor trap body.
- the lid can be connected or detached with the odor trap body, for example by a bayonet closure.
- the lid forms a multi-component element, wherein one of the components of the multi-component element forms a seal to the odor seal body and preferably of a thermoplastic elastomer (TPE) or a vulcanized elastomer having a hardness between 30 and 90 Shore-A exists or as a form element, eg is formed of TPE or an ethylene-propylene-diene rubber (EPDM) or a natural rubber (NR) and bonded to another component of the multi-component element.
- TPE thermoplastic elastomer
- EPDM ethylene-propylene-diene rubber
- NR natural rubber
- the sealing component of the multi-component element is molded onto the other component.
- a particularly good sealing effect can be achieved, and these gaskets are particularly cost-effective due to the integrated production process and the omitted maintenance.
- a component of the multi-component element may consist of a harder material relative to the gasket forming component, such as a gasket.
- the lid has a guide element on which the membrane element is movably arranged and guided.
- a guide element on which the membrane element is movably arranged and guided.
- Guiding element formed as an extension or depression, which cooperates with a recess or an extension of the membrane element.
- the membrane element may be umbrella-like, ie have a straight or curved surface which is bent downwards in its peripheral region.
- the membrane element cooperates with the lid, which may also be designed in the form of a screen.
- the membrane element can only float up to a predefined maximum open position. If the membrane element has a screen-like configuration, the screen covers the outlet opening of the odor closure body or preferably projects beyond it, wherein the membrane element in the closed position sealingly rests on the edge defining the outlet opening and thus a secure sealing effect is guaranteed.
- the invention provides in one embodiment that the membrane element has a specific total weight greater than water. That is, unlike the prior art, the membrane element is not configured as a floating body, whereby the effect is not due to lifting through the water level of the incoming water, but due to the water pressure in the chamber and therefore very reliable. It has been found that the desired effect can best be achieved at pressures commonly encountered in a channel system when the membrane element has a mass of from 5 to 200 grams, preferably from 10 to 150 grams, most preferably from 15 to 40 grams , With such a mass, the membrane element is not raised by negative pressure in the duct system and is also backstop.
- the membrane element Due to its mass, the membrane element ensures tightness even in the dried out condition of the odor trap.
- the membrane element despite reduced compared to the prior art odor trap height to about -200 Pa negative pressure, a suction of the sealing water, with 25 mm sealing water level in the chamber even to -400 Pa negative pressure.
- the membrane element keeps tight to at least 400 Pa and thus prevents the penetration of channel gases into the respective space.

- the membrane element 15 should not be designed as floating on the water level element, but in contrast to have a specific total weight greater than water. However, not only does the specific weight of the membrane element 15 play a role in the function of the odor trap 10, but also its absolute mass in order to be able to reliably control underpressures and overpressures occurring in a channel system. It has been found that to achieve this purpose, the membrane element should have a mass of from 5 to 200 grams, preferably from 10 to 150 grams, most preferably from 15 to 40 grams.

- the odor trap 10 functions such that drain water entering the chamber 12 through the inlet ports 14 and the inlet channels 17 first fills the chamber 12 and forms barrier water therein which keeps the channel gases from passing out of the channel through the odor trap 10 into the environment.
- the outlet opening 13 is initially sealed by the membrane element 15 due to its own weight. Only when the water level in the chamber 12 has risen to approximately the level of the outlet opening 13, the water pressure raises the membrane element 15 and the drain water exits through the outlet opening 13 in the drain chamber 20 which communicates with the channel, as more fully below is explained. If the chamber 12 dries due to a lack of water supply, the membrane element 15 continues to seal the outlet opening 13 by its own weight.

Description
Die Erfindung betrifft einen Geruchsverschluss für einen Wasserablauf sowie einen mit dem Geruchsverschluss versehenen Wasserablauf.The invention relates to an odor trap for a water outlet and provided with an odor trap drainage.
Bei Abläufen mit einem Wasser-Geruchsverschluss besteht das Problem, dass es immer wieder zu einem Austrocknen des Ablaufes kommen kann, wenn dieser für längere Zeit nicht benützt wird. Durch einen ausgetrockneten Wasser-Geruchsverschluss gelangen Kanalgase aus dem Abwassersystem nach außen, und es kommt zu einer intensiven Geruchsbelästigung. Dies tritt zum Beispiel in Ferienhäusern und Hotels, die längere Zeit unbenutzt sind, auf.In the case of processes with a water-odor trap, there is the problem that it can come again and again to dry out the drain, if it is not used for a long time. Through a dried water odor trap channel gases from the sewer system to the outside, and it comes to an intense odor. This occurs, for example, in holiday homes and hotels, which are unused for a long time.

Obwohl sich die bekannten Wasser-Geruchsverschlüsse in der Praxis bewährt haben, weisen sie dennoch einige Nachteile auf. Ein erster Nachteil besteht in ihrer großen Bauhöhe, die einen hohen Bodenaufbau des Gebäudes verlangt. Ein solch hoher Bodenaufbau ist z.B. bei Renovierungen oft nicht realisierbar. Es gibt auch viele Länder, in denen ein entsprechend hoher Bodenaufbau nicht Standard oder nicht praxisgemäß ist.Although the known water-odor seals have been proven in practice, they still have some disadvantages. A first disadvantage is their large height, which requires a high floor structure of the building. Such a high floor structure is often not feasible eg during renovations. There are also many countries in which a correspondingly high floor construction is not standard or not practical.
Um die Bauhöhe der Geruchsverschlüsse zu verringern, werden am Markt auch Geruchsverschlüsse mit gegenüber den Normanforderungen verringerter Sperrwasserhöhe angeboten. Diese miniaturisierten Geruchsverschlüsse weisen jedoch eine geringe Abflussleistung auf. Das Problem der Nicht-Einbaubarkeit von Geruchsverschlüssen aufgrund zu großer Bauhöhe tritt insbesondere auch bei barrierefreien Duschen auf.To reduce the height of the odor traps, odor traps are also offered on the market with reduced sealing height compared to the standard requirements. However, these miniaturized odor traps have a low drainage performance. The problem of non-installability of odor traps due to excessive height occurs especially in barrier-free showers.
Ein weiterer Nachteil der bekannten Wasser-Geruchsverschlüsse mit verringerter Sperrwasserhöhe besteht darin, dass diese Kanalgase durchlassen, wenn im Kanalsystem ein Überdruck herrscht. Die Gründe dafür sind einerseits das Austrocknen des Geruchsverschlusses bei längerer Nichtbenutzung und andererseits die geringe Sperrwasserhöhe bei flachen Geruchsverschlüssen, so dass das Sperrwasser einem Gasüberdruck im Kanal einen zu geringen statischen Druck entgegensetzt und daher den Durchgang von Kanalgasen nicht verhindern kann.Another disadvantage of the known water odor traps with reduced sealing water level is that they pass through the duct gases when there is an overpressure in the duct system. The reasons for this are on the one hand the drying of the odor trap during prolonged non-use and on the other hand, the low sealing water level in shallow odor closures, so that the sealing water opposes a gas pressure in the channel too little static pressure and therefore can not prevent the passage of channel gases.
Die vorliegende Erfindung stellt sich die Aufgabe, die genannten Nachteile der bekannten Wasser-Geruchsverschlüsse zu überwinden oder zumindest zu mildern. Insbesondere soll die Bauhöhe gegenüber den bekannten Geruchsverschlüssen bei gleichzeitiger Beibehaltung einer ausreichenden Ablaufleistung verringert werden. Weiters sollen Kanalgase auch bei einem gewissen Überdruck im Kanalsystem vom Durchgang durch den Geruchsverschluss abgehalten werden. Ebenso soll das Aussaugen des Sperrwassers bei Unterdruck im Kanalsystem vermindert werden.The object of the present invention is to overcome or at least alleviate the said disadvantages of the known water odor traps. In particular, the height should be reduced compared to the known odor trap while maintaining a sufficient drainage capacity. Furthermore, channel gases are to be prevented from passing through the odor trap even with a certain overpressure in the channel system. Likewise, the suction of the sealing water at reduced pressure in the duct system should be reduced.
Diese Aufgabe wird durch einen Geruchsverschluss mit den Merkmalen des Anspruchs 1 und durch einen Wasserablauf mit einem erfindungsgemäßen Geruchsverschluss gelöst. Weitere Ausgestaltungen der Erfindung und die sich daraus ergebenden Vorteile sind in den Unteransprüchen und der nachfolgenden Beschreibung dargelegt.This object is achieved by an odor trap with the features of
Der erfindungsgemäße Geruchsverschluss weist einen Geruchsverschlusskörper auf, der eine Kammer für Sperrwasser definiert, wobei die Kammer zumindest eine Einlassöffnung und zumindest eine Auslassöffnung aufweist, wobei der Geruchsverschluss ein zwischen einer Schließstellung und einer Öffnungsstellung bewegliches Membranelement aufweist, das so im Geruchsverschluss angeordnet ist, dass es in der Schließstellung die zumindest eine Auslassöffnung der Kammer verschließt und in der Öffnungsstellung die zumindest eine Auslassöffnung der Kammer freigibt. Weiters definiert der Geruchsverschlusskörper einen offenen Ablaufraum, der mit der zumindest einen Auslassöffnung der Kammer kommuniziert, wenn sich das Membranelement in der Öffnungsstellung befindet. Der Ablaufraum umgibt die zumindest eine Auslassöffnung der Kammer zumindest teilweise. Die zumindest eine Einlassöffnung bildet einen Einlasskanal, der - in Einbaulage gesehen - ein oberes, zur Umgebung offenes Ende aufweist und sich nach unten in einen unteren Bereich der Kammer erstreckt, wobei der Einlasskanal den Ablaufraum zumindest teilweise umgibt.The odor trap according to the invention has an odor trap body defining a chamber for sealing water, wherein the chamber has at least one inlet opening and at least one outlet opening, wherein the odor trap has a membrane element movable between a closed position and an open position, which is arranged in the odor trap such that it in the closed position closes the at least one outlet opening of the chamber and in the open position releases the at least one outlet opening of the chamber. Furthermore, the odor seal body defines an open drain space that communicates with the at least one outlet opening of the chamber when the membrane element is in the open position. The drainage chamber at least partially surrounds the at least one outlet opening of the chamber. The at least one inlet opening forms an inlet channel which, viewed in the installation position, has an upper end open to the environment and extends downwards into a lower region of the chamber, the inlet channel at least partially surrounding the discharge chamber.
Dieser Geruchsverschluss bietet den großen Vorteil, dass bei Überdruck im Kanal, der sich im Ablaufraum des Geruchsverschlusses manifestiert, das Membranelement gegen die Auslassöffnung des Geruchsverschlusskörpers angedrückt wird und die Auslassöffnung daher noch fester verschließt. Ein weiterer Vorteil des Geruchsverschlusses ist seine geringe Bauhöhe durch das Vorsehen und die Positionierung der Einlasskanäle seitlich vom Ablaufraum. Der offene Ablaufraum ermöglicht auch Einbaulagen des Geruchsverschlusses in jeder Drehrichtung um seine vertikale Achse, d.h. der Einbau kann in 360° Drehung erfolgen, wenn der Geruchsverschluss eine zylindrische Form aufweist.This trap has the great advantage that in case of overpressure in the channel, which manifests itself in the drainage chamber of the odor trap, the membrane element is pressed against the outlet opening of the odor trap body and therefore closes the outlet even more firmly. Another advantage of the trap is its low height by the provision and positioning of the inlet channels laterally from the drainage chamber. The open drainage space also allows mounting positions of the odor trap in each direction of rotation about its vertical axis, i. the installation can be done in 360 ° rotation, if the odor trap has a cylindrical shape.
Eine kompakte Bauweise des Geruchsverschlusses kann erzielt werden, wenn die zumindest eine Auslassöffnung der Kammer in einer inneren Kammerumfangswand des Geruchsverschlusskörpers ausgebildet ist, wobei die Außenseite der inneren Kammerumfangswand einen Teil des Ablaufraums definiert. Aus konstruktiven Gründen und zur Erzielung einer hohen Ablaufleistung durch kurze Strömungspfade ist es bevorzugt, wenn die Auslassöffnung durch ein oberes, offenes Ende der inneren Kammerumfangswand gebildet ist.A compact construction of the odor trap can be achieved when the at least one outlet opening of the chamber is formed in an inner chamber peripheral wall of the odor trap body, wherein the outer side of the inner chamber peripheral wall defines a part of the drain space. For structural reasons and to achieve a high drainage capacity through short flow paths, it is preferred if the outlet opening is formed by an upper, open end of the inner chamber peripheral wall.
Um eine kompakte Bauweise und geringe Bauhöhe des Geruchsverschlusses zu realisieren, ist in einer Ausführungsform vorgesehen, dass die Außenseite eines Wandabschnitts des zumindest einen Einlasskanals einen Teil des Ablaufraums definiert.In order to realize a compact design and low overall height of the odor trap, it is provided in one embodiment that the outside of a wall portion of the at least one inlet channel defines a part of the drainage space.
In einer bevorzugten Ausgestaltung des erfindungsgemäßen Geruchsverschlusses sind zumindest zwei Einlasskanäle vorgesehen, die die Auslassöffnung abschnittsweise umgebend voneinander beabstandet angeordnet sind. Diese Ausführungsform bietet den Vorteil einer großen Ablaufleistung bei gleichzeitig weiter reduzierter Bauhöhe. Wenn zwei Einlasskanäle vorgesehen sind, so sind diese bevorzugt um 180° zueinander versetzt, d.h. in Bezug auf den Ablaufraum und die Auslassöffnung des Geruchsverschlusskörpers einander gegenüberliegend angeordnet und umgeben bevorzugt den zumindest einen Ablauf abschnittsweise.In a preferred embodiment of the odor trap according to the invention, at least two inlet channels are provided, which are arranged spaced apart from one another and surround the outlet opening. This embodiment offers the advantage of a large drainage capacity while further reduced height. If two inlet channels are provided, these are preferably offset by 180 ° from one another, ie arranged opposite one another with respect to the outlet space and the outlet opening of the odor trap body, and preferably surround the at least one outlet in sections.
In einer alternativen Ausführungsform, die ebenfalls eine große Ablaufleistung bei reduzierter Bauhöhe bietet, sind zumindest zwei Auslassöffnungen vorgesehen, die den Einlasskanal abschnittsweise umgebend voneinander beabstandet angeordnet sind.In an alternative embodiment, which also offers a large drainage capacity with reduced overall height, at least two outlet openings are provided, which are arranged circumferentially spaced apart from each other the inlet channel.
Es ist weiters bevorzugt, dass der Geruchsverschluss einen Deckel aufweist, der abnehmbar an dem Geruchsverschlusskörper angeordnet ist, wobei der Deckel einen - in Einbaulage des Geruchsverschlusses - oberen Abschnitt des Ablaufraums definiert und diesen oberen Abschnitt in Kooperation mit dem Geruchsverschlusskörper nach oben gegenüber der Umgebung abdichtet. Der Deckel kann für Inspektionszwecke ein transparentes Fenster aufweisen oder aus einem transparenten Material bestehen. Da der Deckel abnehmbar ist, ist das Membranelement für Wartung und Tausch leicht zugänglich. Die Inspektionsmöglichkeit bei Vorsehen eines transparenten Deckels ermöglicht eine rasche Kontrolle der Funktionsfähigkeit und allfälliger Verschmutzung des Geruchsverschlusskörpers. Der Deckel kann mit dem Geruchsverschlusskörper beispielsweise durch einen Bajonettverschluss verbunden bzw. gelöst werden.It is further preferred that the odor trap has a lid which is removably disposed on the odor trap body, the lid defines a - in installation position of the odor trap - upper portion of the drain space and seals this upper portion in cooperation with the odor trap body upwards from the environment , The lid may have a transparent window for inspection purposes or be made of a transparent material. Since the lid is removable, the membrane element is easily accessible for maintenance and replacement. The possibility of inspection with the provision of a transparent lid allows a rapid control of the functionality and any contamination of the odor trap body. The lid can be connected or detached with the odor trap body, for example by a bayonet closure.
Es ist weiters bevorzugt, dass der Deckel ein Mehr-Komponenten-Element bildet, wobei eine der Komponenten des Mehr-Komponenten-Elements eine Dichtung zum Geruchsverschlusskörper bildet und vorzugsweise aus einem thermoplastischen Elastomer (TPE) oder einem vulkanisierten Elastomer mit einer Härte zwischen 30 und 90 Shore-A besteht oder als ein Formelement, z.B. aus TPE oder einem Ethylen-Propylen-Dien-Kautschuk (EPDM) oder einem Naturkautschuk (NR) ausgebildet und mit einer anderen Komponente des Mehr-Komponenten-Elements verbunden ist. Das Verbinden erfolgt z.B. durch Kleben, Schweißen oder Formschluss (insbesondere, wenn das Formelement als O-Ring ausgebildet ist, der in einer Nut der anderen Komponente positioniert ist). Besonders vorteilhaft wird die Dichtungskomponente des Mehr-Komonenten-Elements an die andere Komponente angespritzt. Hierdurch ist eine besonders gute Dichtwirkung zu erzielen, und durch den integrierten Herstellprozess sowie die wegfallende Wartung sind diese Dichtungen besonders kostengünstig. Es ist weiters vorgesehen, dass eine Komponente des Mehr-Komponenten-Elements aus einem relativ zu der die Dichtung bildenden Komponente härteren Material, wie z.B. Polypropylen (PP), Acrylnitril-Butadien-Styrol-Copolymeren (ABS) oder Polyamid (PA), besteht. Dies verleiht dem Deckel Stabilität und Formbeständigkeit.It is further preferred that the lid forms a multi-component element, wherein one of the components of the multi-component element forms a seal to the odor seal body and preferably of a thermoplastic elastomer (TPE) or a vulcanized elastomer having a hardness between 30 and 90 Shore-A exists or as a form element, eg is formed of TPE or an ethylene-propylene-diene rubber (EPDM) or a natural rubber (NR) and bonded to another component of the multi-component element. The connection takes place e.g. by gluing, welding or positive locking (in particular if the shaped element is designed as an O-ring, which is positioned in a groove of the other component). Particularly advantageously, the sealing component of the multi-component element is molded onto the other component. As a result, a particularly good sealing effect can be achieved, and these gaskets are particularly cost-effective due to the integrated production process and the omitted maintenance. It is further contemplated that a component of the multi-component element may consist of a harder material relative to the gasket forming component, such as a gasket. Polypropylene (PP), acrylonitrile-butadiene-styrene copolymers (ABS) or polyamide (PA). This gives the lid stability and dimensional stability.
Zur Erhöhung der Funktionssicherheit des erfindungsgemäßen Geruchsverschluss kann vorgesehen sein, dass der Deckel ein Führungselement aufweist, an dem das Membranelement beweglich angeordnet ist und geführt wird. Vorzugsweise ist das Führungselement als Fortsatz oder Vertiefung ausgebildet, der/die mit einer Vertiefung bzw. einem Fortsatz des Membranelements zusammenwirkt. Wie in einer in der Zeichnung dargestellten Ausführungsform des erfindungsgemäßen Geruchsverschlusses dargestellt, kann das Membranelement schirmartig ausgebildet sein, d.h. eine gerade oder gekrümmte Fläche aufweisen, die in ihrem Umfangsbereich nach unten gebogen ist. Das Membranelement wirkt mit dem Deckel zusammen, der ebenfalls in Form eines Schirms ausgebildet sein kann. Durch das Vorsehen eines Führungselements am Deckel ergibt sich eine verlässliche Führung der Bewegung des Membranelements beim Öffnen und Schließen der Auslassöffnung. Zusätzlich ist gewährleistet, dass bei Wasserzufluss durch die Einlasskanäle das Membranelement nur bis zu einer vordefinierten maximalen Öffnungsstellung aufschwimmen kann. Wenn das Membranelement eine schirmartige Konfiguration aufweist, so bedeckt der Schirm die Auslassöffnung des Geruchsverschlusskörpers bzw. überragt sie bevorzugt, wobei das Membranelement in der Schließstellung auf dem die Auslassöffnung begrenzenden Rand dichtend aufliegt und damit eine sichere Dichtwirkung garantiert ist.To increase the functional reliability of the odor trap according to the invention, it can be provided that the lid has a guide element on which the membrane element is movably arranged and guided. Preferably that is Guiding element formed as an extension or depression, which cooperates with a recess or an extension of the membrane element. As shown in an embodiment of the odor trap according to the invention shown in the drawing, the membrane element may be umbrella-like, ie have a straight or curved surface which is bent downwards in its peripheral region. The membrane element cooperates with the lid, which may also be designed in the form of a screen. The provision of a guide element on the lid results in reliable guidance of the movement of the membrane element during opening and closing of the outlet opening. In addition, it is ensured that when water flows through the inlet channels, the membrane element can only float up to a predefined maximum open position. If the membrane element has a screen-like configuration, the screen covers the outlet opening of the odor closure body or preferably projects beyond it, wherein the membrane element in the closed position sealingly rests on the edge defining the outlet opening and thus a secure sealing effect is guaranteed.
Für eine hohe Funktionssicherheit des erfindungsgemäßen Geruchsverschluss bei unterschiedlichen Druckverhältnissen im Kanalsystem sieht die Erfindung in einer Ausführungsform vor, dass das Membranelement ein spezifisches Gesamtgewicht größer als Wasser aufweist. Das heißt, dass anders als beim Stand der Technik das Membranelement nicht als Schwimmkörper konfiguriert ist, wodurch die Wirkung nicht auf Hochheben durch den Wasserspiegel des einlaufenden Wassers beruht, sondern durch den Wasserdruck in der Kammer bedingt und daher sehr verlässlich ist. Es hat sich gezeigt, dass die gewünschte Wirkung bei den in einem Kanalsystem üblicherweise vorherrschenden Drücken am besten erzielt werden kann, wenn das Membranelement eine Masse von 5 bis 200 Gramm, vorzugsweise von 10 bis 150 Gramm, am bevorzugtesten von 15 bis 40 Gramm, aufweist. Mit einer solchen Masse wird das Membranelement auch nicht durch Unterdruck im Kanalsystem angehoben und ist auch rückstaudicht. Durch seine Masse sorgt das Membranelement auch im ausgetrockneten Zustand des Geruchsverschlusses für Dichtheit. Insbesondere verhindert das Membranelement trotz gegenüber dem Stand der Technik verringerter Geruchsverschlusshöhe bis ca. -200 Pa Unterdruck ein Aussaugen des Sperrwassers, mit 25 mm Sperrwasserhöhe in der Kammer sogar bis -400 Pa Unterdruck. Bei Überdruck im Kanal hält das Membranelement bis zumindest 400 Pa dicht und verhindert somit das Eindringen von Kanalgasen in den jeweiligen Raum.For a high reliability of the odor trap according to the invention at different pressure ratios in the duct system, the invention provides in one embodiment that the membrane element has a specific total weight greater than water. That is, unlike the prior art, the membrane element is not configured as a floating body, whereby the effect is not due to lifting through the water level of the incoming water, but due to the water pressure in the chamber and therefore very reliable. It has been found that the desired effect can best be achieved at pressures commonly encountered in a channel system when the membrane element has a mass of from 5 to 200 grams, preferably from 10 to 150 grams, most preferably from 15 to 40 grams , With such a mass, the membrane element is not raised by negative pressure in the duct system and is also backstop. Due to its mass, the membrane element ensures tightness even in the dried out condition of the odor trap. In particular, the membrane element, despite reduced compared to the prior art odor trap height to about -200 Pa negative pressure, a suction of the sealing water, with 25 mm sealing water level in the chamber even to -400 Pa negative pressure. In the event of overpressure in the channel, the membrane element keeps tight to at least 400 Pa and thus prevents the penetration of channel gases into the respective space.
Zur Realisierung einer wartungsfreien Abdichtung der zumindest einen Auslassöffnung durch das Membranelement ist das Membranelement vorzugsweise durch ein Mehr-Komponenten-Element, insbesondere ein Kunststoff-Verbundmaterial mit einer Dichte von mehr als 1000 kg/m3, gebildet, wobei eine Komponente, die in der Schließ stellung auf dem die Auslassöffnung begrenzenden Rand dichtend aufliegt, aus einem Dichtungsmaterial besteht, vorzugsweise aus einem thermoplastischen Elastomer (TPE) oder einem vulkanisierten Elastomer mit einer Härte zwischen 30 und 90 Shore-A, oder als ein Formelement, z.B. aus TPE oder EPDM oder NR, ausgebildet und mit einer anderen Komponente des Mehr-Komponenten-Elements verbunden ist. Die Verbindung kann z.B. durch Anspritzen, Kleben, Schweißen oder formschlüssig erfolgen. Der Vorteil einer solchen Ausgestaltung des Membranelements liegt in der Realisierung einer in das Membranelement integrierten, wartungsfreien Dichtung. Um dem Membranelement Stabilität und Formbeständigkeit zu verleihen, ist vorgesehen, dass eine Komponente des Mehr-Komponenten-Elements des Membranelements aus einem relativ zu der die Dichtung bildenden Komponente härteren Material, wie z.B. Polypropylen (PP), Acrylnitril-Butadien-Styrol-Copolymeren (ABS) oder Polyamid (PA), besteht.In order to realize a maintenance-free sealing of the at least one outlet opening by the membrane element, the membrane element is preferably formed by a multi-component element, in particular a plastic composite material with a density of more than 1000 kg / m 3 , formed, wherein a component, the sealing position in the closed position on the edge bounding the outlet opening, is made of a sealing material, preferably of a thermoplastic elastomer (TPE) or a vulcanized elastomer having a hardness between 30 and 90 Shore A, or as a shaped element, for example made of TPE or EPDM or NR, and connected to another component of the multi-component element. The connection can be made, for example, by injection molding, gluing, welding or positive locking. The advantage of such an embodiment of the membrane element lies in the realization of a maintenance-free seal integrated into the membrane element. In order to provide the membrane element with stability and dimensional stability, it is provided that a component of the multi-component element of the membrane element consists of a material which is harder relative to the component forming the seal, for example polypropylene (PP), acrylonitrile-butadiene-styrene copolymers ( ABS) or polyamide (PA).
Zur Einstellung der Masse des Membranelements ist es zweckmäßig, wenn das Membranelement ein metallisches Material, wie z.B. Messing, Bronze, Magnetit, Kupfer, oder ein anorganisches Material, wie z.B. Bariumsulfat umfasst, oder Gewichtseinsätze, insbesondere aus den genannten Materialien, aufweist.To adjust the mass of the membrane element, it is expedient for the membrane element to comprise a metallic material, such as e.g. Brass, bronze, magnetite, copper, or an inorganic material, e.g. Barium sulfate, or weight inserts, in particular from the materials mentioned, has.
Zur Erhöhung der Funktionssicherheit des Geruchsverschlusses und für eine leichte Reinigung ist in einer Ausführungsform der Erfindung die zumindest eine Einlassöffnung der Kammer von einem Haarfangsieb abgedeckt, wobei das Haarfangsieb bevorzugt in den Deckel integriert ist, alternativ dazu aber auch abnehmbar ausgeführt sein kann. Diese Ausführungsform mit Haarfangsieb garantiert eine verlängerte und sichere Funktion des Geruchsverschlusses ohne Wartung, weil im einlaufenden Wasser enthaltene Fremdkörper vom Haarfangsieb zurückgehalten und leicht entfernt werden können.To increase the reliability of the odor trap and for easy cleaning, in one embodiment of the invention, the at least one inlet opening of the chamber is covered by a hair trap, wherein the hair trap is preferably integrated in the lid, but alternatively can also be designed to be removable. This embodiment with hair trap ensures a prolonged and safe function of the odor trap without maintenance, because foreign bodies contained in the incoming water can be retained by the hair trap and easily removed.
Die Erfindung umfasst auch einen Wasserablauf mit einem Ablaufkörper mit einem Anschlussrohr zum Kanal, der mit einem erfindungsgemäßen Geruchsverschluss kombiniert ist. Es ist vorgesehen, dass der Geruchsverschluss entweder in einem im Ablaufkörper ausgebildeten Sitz, oder in einem in einem Einsatz des Wasserablaufs ausgebildeten Sitz, oder in einem in einem Aufsatz des Wasserablaufs ausgebildeten Sitz aufgenommen ist. Um eine 100% geruchsdichte Verbindung zwischen dem Wasserablauf und dem Geruchsverschluss herzustellen, ist der Aufsatz oder Einsatz des Wasserablaufs mit dem Ablaufkörper dicht zu verbinden.The invention also includes a water outlet with a drain body with a connecting pipe to the channel, which is combined with an odor trap according to the invention. It is envisaged that the odor trap is accommodated either in a seat formed in the drain body, or in a seat formed in an insert of the water drain, or in a seat formed in an attachment of the water drain. In order to produce a 100% odor-tight connection between the water outlet and the odor trap, the attachment or use of the water drain is to be tightly connected to the drain body.
Die Erfindung wird nun unter Bezugnahme auf die Zeichnungen beispielhaft näher erläutert. In den Zeichnungen zeigen:

Obwohl bei der beschriebenen Ausführungsform des erfindungsgemäßen Geruchsverschlusses 10 nur zwei Einlasskanäle 17 vorgesehen sind, sieht die Erfindung auch eine größere Zahl an Einlasskanälen 17 vor, wenn dies aus konstruktiven Gründen zweckmäßig ist. Die Einlasskanäle 17 sollen die zumindest eine Auslassöffnung 13 abschnittsweise umgebend voneinander beabstandet angeordnet sein.Although only two
Am Geruchsverschlusskörper 11 ist ein abnehmbarer Deckel 22 angeordnet, der einen oberen Abschnitt des Ablaufraums 20 definiert. Der Deckel 22 kann mit dem Geruchsverschlusskörper 11 beispielsweise durch eine Steckverbindung oder eine Bajonettverbindung lösbar verbunden sein. Weiters kann für eine erleichterte Inspektion des Geruchsverschlusses 10 der Deckel 22 ein transparentes Fenster aufweisen oder aus einem transparenten Material bestehen.At the
In einer bevorzugten Ausführungsform ist der Deckel 22 als ein Mehr-Komponenten-Element gefertigt, wobei eine der Komponenten 23 des Mehr-Komponenten-Elements eine Dichtung zum Geruchsverschlusskörper 11 bildet und vorzugsweise aus einem thermoplastischen Elastomer (TPE) oder einem vulkanisierten Elastomer mit einer Härte zwischen 30 und 90 Shore-A besteht oder als ein Formelement, z.B. aus TPE oder einem Ethylen-Propylen-Dien-Kautschuk (EPDM) oder einem Naturkautschuk (NR) ausgebildet und mit einer anderen Komponente des Mehr-Komponenten-Elements verbunden ist.In a preferred embodiment, the
Eine zweite Komponente 24 des Mehr-Komponenten-Elements besteht bevorzugt aus einem relativ zu der die Dichtung bildenden Komponente 23 härteren Material, wie z.B. Polypropylen (PP), Acrylnitril-Butadien-Styrol-Copolymeren (ABS) oder Polyamid (PA). Es sei darauf hingewiesen, dass auch der Geruchsverschlusskörper 11 aus einem der genannten Materialien gebildet sein kann.A
Im Deckel 22 ist ein als nach unten ragender Fortsatz ausgebildetes Führungselement 25 vorgesehen, entlang dem das Membranelement 15 nach oben und unten beweglich angeordnet ist. Dazu weist das Membranelement 15 eine zentrale Vertiefung 26 auf, die mit dem Führungselement 25 des Deckels 22 so zusammenwirkt, dass das Membranelement 15 sich zwar nach oben und unten bewegen (und je nach Querschnittsform von Fortsatz und Vertiefung auch drehen) kann, nicht jedoch verkippen kann. Wie man aus
Anders als bei den bekannten Geruchsverschlüssen soll das Membranelement 15 nicht als auf dem Wasserspiegel schwimmendes Element ausgebildet sein, sondern im Gegensatz dazu ein spezifisches Gesamtgewicht größer als Wasser aufweisen. Für die Funktion des Geruchsverschlusses 10 spielt aber nicht nur das spezifische Gewicht des Membranelements 15 eine Rolle, sondern auch dessen absolute Masse, um in einem Kanalsystem auftretende Unter- und Überdrücke sicher beherrschen zu können. Es hat sich gezeigt, dass zur Erreichung dieses Zwecks das Membranelement eine Masse von 5 bis 200 Gramm, vorzugsweise von 10 bis 150 Gramm, am bevorzugtesten von 15 bis 40 Gramm, aufweisen soll. Für die Einstellung der Masse des Membranelements 15 kann dieses ein metallisches Material, wie z.B. Messing, Bronze, Magnetit, Kupfer, oder ein anorganisches Material, wie z.B. Bariumsulfat umfassen, oder Gewichtseinsätze, insbesondere aus den genannten Materialien, aufweisen. Um Fremdkörper vom Eindringen in die Kammer 12 abzuhalten, ist ein Haarfangsieb 29 vorgesehen, das entweder in den Deckel 22 integriert ist oder, wie bei der in

Der Geruchsverschluss 10 funktioniert auf die Art, dass durch die Einlassöffnungen 14 und die Einlasskanäle 17 in die Kammer 12 einlaufendes Abflusswasser zunächst die Kammer 12 füllt und darin Sperrwasser bildet, das Kanalgase vom Durchtritt aus dem Kanal durch den Geruchsverschluss 10 in die Umgebung abhält. Die Auslassöffnung 13 ist zunächst durch das Membranelement 15 aufgrund dessen Eigengewichts dicht verschlossen. Erst wenn der Wasserspiegel in der Kammer 12 bis ungefähr auf die Höhe der Auslassöffnung 13 gestiegen ist, hebt der Wasserdruck das Membranelement 15 hoch und das Ablaufwasser tritt durch die Auslassöffnung 13 in den Ablaufraum 20 aus, der mit dem Kanal kommuniziert, wie nachfolgend noch genauer erläutert wird. Trocknet die Kammer 12 aufgrund längerer fehlender Wasserzufuhr aus, so dichtet das Membranelement 15 durch sein Eigengewicht die Auslassöffnung 13 weiterhin ab. Herrscht im Kanal Überdruck, der sich bis in den Ablaufraum 20 fortpflanzt, so drückt der Überdruck das Membranelement 15 nur umso fester gegen die Ränder der Auslassöffnung 13. Herrscht jedoch im Kanal ein Unterdruck, so verhindert die Masse des Membranelements 15, dass es vom Unterdruck hochgehoben wird.The

Damit das Membranelement 35 in der Schließstellung auf dem die Auslassöffnung 33 begrenzenden Rand der inneren Kammerumfangswand 38 sicher dichtend aufliegt, ist vorgesehen, das Membranelement 35 als ein Mehr-Komponenten-Element herzustellen, insbesondere einem Kunststoff-Verbundmaterial mit einer Dichte von mehr als 1000 kg/m3. Eine Komponente 47, die in der Schließstellung auf dem die Auslassöffnung 33 begrenzenden Rand aufliegt, besteht dabei aus einem Dichtungsmaterial, vorzugsweise aus einem thermoplastischen Elastomer (TPE) oder einem vulkanisierten Elastomer mit einer Härte zwischen 30 und 90 Shore-A.
